Only the first slide was visible when viewed in Firefox 3.6.3 and Chrome 4.1... It's Hard to believe that something so unviewable made it to the front page of HN.
You have to push the right arrow key, it's a slide show. Sorry for not having better instructions, it's based off of the http://apirocks.com/html5/html5.html#slide1 presentation. The reason mouse clicks can't be used is because that would interfere with the JavaScript examples later on in the presentation.
Impressive work, Matthew! And I'm pleased it led me to your "Prosper" db front-end: looking forward to following its development. ...and to your use of "unlicense'd" (did i get right number/type of quotes?).
Thank you for your kind words, yes I believe that all of your quotes match up nicely. I can't take all the credit, this is based heavily on the apirocks HTML5 slideshow and on the amazing work Paul Irish did on the jQuery 1.4 Hawtness series, standing on the shoulders of giants.
